In IOWQIiHg' a boat this link 9 isswung back out of operative positionto permit of the automatic release of the hook from the eye as previously described.

I provide a means for holding the fall block 3 centered and the blockandhoat properly spaced from the side of the ship, whereby the boat is lashedto the ship andrestrained from swinging toward or from the same whilebeing lowered." To'this'e'nd I employ a restraining'device 11 in the form 1 teringthe blockand holding the boat from swinging movement, said meansinoluc'ling-75 of a rod corn'p'osed of's'ections 12and'l3 threaded at their inner ends to receive a" turn buckle 14, {whereby the'lefngtli of the rod may be varied as required. The outer end' ofthe rod section 12 isvprov'ided with a hook 15 to engage an eye 16fon thefall' block 3, while the relatively outer end of the rod section 13 is' provided with an eye '17 piy otally engaging a coupling member or staple 18011 a for ding-plate 19.
